An actual dispute between individuals who seek judicial resolution of their grievances that have arisen from a conflict of their alleged legal rights.
A controversy describes only civil litigation, which is intended to protect and enforce private rights. In contrast, the term case applies to both a civil action and a criminal prosecution, designed to enforce and safeguard the rights of the general public.
The judicial power of a court to provide redress of wrongs exists only when issues arise in a given situation that can be categorized as a case or controversy.
